Calculated distance value to change

Assignment Help Basic Computer Science
Reference no: EM133220503

In a high-quality coaxial cable, the power drops by a factor of 10 approximately every 2.75 km. If the original signal power is 0.45 W (= 4.5 x 10-1), how far will a signal be transmitted before the power is attenuated to 45 μW?

Include a table showing the signal power (in W) vs distance in 2.75 km intervals (like Table 1.2 in Section 1.4.4) as part of your answer.

If optical fibre is used instead of the coaxial cable, briefly explain how you would expect the above calculated distance value to change (see Section 1.4.4).
